Rack middleware is more than "a way to filter a request and response" - it's an implementation of the pipeline design pattern for web servers using Rack.
It very cleanly separates out the different stages of processing a request - separation of concerns being a key goal of all well designed software products.

2 to 4 percentage points off the rates districts were reporting because they were improperly counting some types of students who shouldn’t be included, such as those who started home schooling in their junior year of high school.

"Home School" at such beginning in junior year is the equivalent of "counseling out" students...

2 to 4 percentage points adds up quick, even for smaller states since often those emerging adults would most likely have significant holes in knowledge and skills. Otherwise, why would 4% of juniors all-of-a-sudden decide to be "home schooled"?

The oil discovered in the Prudhoe Bay oil field in the North Slope region of Alaska in 1968 was the “largest oil field discovered in North America.” In 1969, a Trans-Alaska pipeline to transport oil from the North Slope was proposed by the Trans-Alaska Pipeline System. The Trans-Alaska Pipeline System was comprised of three major oil corporations. Despite many other ideas and suggestions to transport this oil, the oil industry reached a consensus in favor of the pipeline proposal of the Trans-Alaska Pipeline System (Busenberg, 2013). Construction of the Alyeska oil pipeline, also known as the Alaska pipeline or trans-Alaska pipeline, began in 1975. This pipeline was built by the Alyeska Pipeline Service Company, a group that was made up of seven different oil companies. In certain regions, the pipeline is buried underground, but where there is permafrost, the pipeline is constructed above the ground. The pipeline crosses over 800 river and streams and passes through three mountain ranges. The first oil was delivered from Prudhoe Bay to Valdez on June 20, 1977. This oil had to travel through the 789 mile long pipeline to reach its destination (Alaska Public Lands Information Centers, n.d.). See below for a link to “Pipeline! The story of the building of the trans-Alaska pipeline” video posted on YouTube by the Alaska National Parks service.

Designed during the first months of World War II, the Canol Pipeline brought oil from Norman Wells near the Mackenzie River to Whitehorse, Yukon Territory. Once the oil was refined, it would be sent to Alaska via pipeline to ensure that the Japanese navy could not intercept any transport. The oil deposits at Norman Wells were discovered by the explorer Alexander Mackenzie during the 18th century. In January of 1942, Lieutenant General Brehon Somervell, commanding general of the Army Service Forces, ordered James H. Graham, former dean of engineering at the University of Kentucky, to investigate the possibility of harvesting oil from Norman Wells. On April 29, 1942, General Somervell immediately approved the recommendation of Dean Graham to implement a pipeline from Norman Wells to Whitehorse (O'Brien, 1970). The construction began in 1942 and was completed in 1944 by the United States Army. A road was also constructed alongside the Canol pipeline during this time. In 1945, soon after the completion of the Canol Pipeline, the volume of crude oil that was able to be transported compared to the cost of operating the pipeline could not be justified. The Canol Pipeline was shut down and abandoned in 1945 (Wilson, 1991).

The Medvezhye Pipeline is a pipeline built on the Medvezhye oil and gas field (Shabad). This naturally occurring gas field is located in Northern Siberia. Officials hoped the institution of the pipeline would provide industrial Russian communities with oil by the late 1970s. Siberia also signed contracts with Italy, France, and West Germany and agreed to provide natural gas in exchange for pipes. The pipeline was built in a sub-Arctic region with harsh weather and frozen ground and many worried that the pipeline would not be constructed according to schedule. The Medvezhye pipeline was constructed on warming, unstable permafrost. The pipeline was commissioned in 1972 and is Russia’s third most highly producing pipeline (Seligman). In 1977, a study was performed to measure pipe deformation due to warming permafrost conditions. No deformation was found due to the pipe’s thickness. As of 2011, the pipeline’s managers, Victoria Oil and Gas PLC, reported that the pipeline had 400 million barrels of oil in place (Victoria Oil and Gas). In continued monitoring and development of the pipeline, Victoria Oil and Gas also performed studies to determine possible new drilling and well sites, production infrastructure, and downstream hydrocarbon emissions effects. Victoria Oil and Gas also studied oil export from the pipeline to Siberia and other parts of Russia. Today, the pipeline is still a major source of oil and gas for Russia.

The Trans-Alaska Pipeline Project began construction on March 27, 1975. The pipeline was constructed in response to the discovery of oil under the Purdhoe Bay (Alaska Public Lands Information Centers). The project was controversial because environmentalists worried about earthquakes and the effects on elk migrations (Wells). The pipeline is almost 800 miles long and includes pumping stations that connected other pipelines. The pipeline was constructed by the Alyeska Pipeline Service Company, which was created by seven oil companies (Wells, Alaska Public Lands Information Centers). The pipeline is mostly below ground, except in areas of permafrost. The sections of pipe that were built above ground were built in a zigzag pattern to account for expansion due to temperature changes (Wells). In unseasonably warm areas, the pipeline is supported by two thicker “heat pipes.” The pipeline was completed on May 31, 1977 (Alaska Public Lands Information Centers). The pipeline first contained oil on June 20, 1977. The pipeline carries about 1.8 million barrels of oil per day. In March of 1989, an oil tanker leaked over 260,000 barrels of oil into the Prince William Sound. This was the second largest oil spill in the United States. The spill covered 1300 miles of land and 11,000 miles of ocean. Images of the pipeline can be seen below.

This map shows the 800-mile Trans-Alaska Pipeline System (TAPS), also called the Alyeska Pipeline, that was built in the 1970s with 11 pumping stations that transports crude oil from Prudhoe Bay to Port Valdez. The pipeline cost around $8 billion to build. The link below provides facts on the pipeline provided by the Alyeska Pipeline Service Company:

Carson H. Templeton was born in Wainwright, Alberta. He earned a diploma studying Mining Engineering at the Southern Alberta Institute of Technology (SAIT) in Calgary, Alberta. He worked at the Madsen Red Lake Mine in Northwest Ontario as an Assistant Assayer, Boat Boy, and Post Office Manager. He attended the University of Alberta to continue his studies of Mining Engineering and graduated with a Bachelor of Science. During World War II, Templeton worked on the Canol Pipeline Project. He then helped construct airports alongside the Alaska Highway for military use. In 1948, Templeton was appointed Assistant Chief Engineer of the Fraser Valley Dyking Board. In 1950, Templeton was appointed Chief Engineer of the Greater Winnipeg Dyking Board. In 1955, Templeton founded a consulting engineering firm which he named the Templeton Engineering Company. Before the Unicity Amalgamation of Winnipeg in 1972, his company worked as the City Engineer for several small cities in Canada. His company performed engineering estimates for the Royal Commission on Flood Cost-Benefits. These calculations led to the construction of the Winnipeg Floodway. Additionally, Carson Templeton’s consulting engineering firm conducted research that supported the writing of “Snow and Ice Roads: Ability to Support Traffic and Effects on Vegetation” by Kenneth Adam and Helios Hernandez (Adam and Hernandez 1977). In 1966, his company merged with Montreal Engineering and Shawinigan Engineering to form Teshmont Consultants Ltd. Teshmont Consultants Ltd. has completed over 50 percent of the world’s high-voltage, direct current projects. Templeton served as the Chairman of the Alaska Highway Pipeline Panel and Chairman of the Environmental Protection Board during the 1970s. As the Chairman of the Environmental Protection Board, Templeton orchestrated the hearing process for the Environmental Impact Assessments for the Mackenzie Valley Pipeline Inquiry (Winnipeg Free Press 2004).

The Pointed Mountain Pipeline is a 34.2-mile long natural gas pipeline that connects a dehydration plant at Beaver River in British Columbia, with another plant at Pointed Mountain in the Northwest Territories (Landeen, Brandt). The pipeline extends across British Columbia, the Yukon, and the Northwest Territories. The pipeline crosses the Kotaneelee and La Biche Rivers. Construction on the pipeline began January 24, 1972 and the pipeline was completed in March of 1972, but was not in operation. Throughout the construction of the pipeline, scientists worried about the environmental factors of the pipeline, such as permafrost melting, bank instability, and siltation of rivers. The pipeline was built through a permafrost region. Because the natural gas has the ability to melt the permafrost, weights were attached to the pipe to prevent it from surfacing. Scientists were concerned about bank instability due to erosion when the pipeline crossed the Kotaneelee River. Sandbags supported the pipeline in order to increase stability. Drainage pipes were also added to prevent erosion. Scientists were also concerned about the high water levels in the rivers during spring thaw. The pipes were placed in a deep trench, surrounded by concrete to prevent rising of the pipes during flooding. The trench then fills in with water to prevent river overflow. A map showing the installation of the pipeline can be found below:

In this statement, Berger, is reassuring the reader by attempting to instill an air of patience. Although it may have been possible to argue this statement when it was written, today we can definitively say that the resources are still there. It’s difficult to know if Berger really thought that after 40 years the energy companies are still figuring out the details of this project. Although many of the land claims that were so pivotal in arguing the moratorium have been settled decades ago, there are still economic social and logistical barriers yet to be worked out. Nevertheless, energy companies continue to knock on the door of the Canadian Arctic. For example, In 2005 a government appointed Joint Review Panel completed and approved a five year survey of a recently proposed pipeline through the Mackenzie Valley. This approval was conditional upon the implementation of 176 recommendations including enviro-social aspects. This review had mimicked similar style to that of the original Berger Inquiry and sought the diverse voices and opinions of the Mackenzie Valley. Although support wasn’t unanimous there was clear shift in opinion of the pipeline since the original inquiry. However, as recently as 2016 Imperial Oil Resources Ventures Ltd. was approved for an extension to the construction of their proposed pipeline through the Mackenzie Valley citing the market conditions of natural gas as the primary inhibiting factor. This shows that to this day, not for lack of trying, the words of Thomas Berger still ring true “The resources will still be there”.

The Canadian Arctic Resource Committee (CARC) is an organization that is run by and serves the citizens of Canada in regard to environmental and social changes. CARC was originally developed in 1987 in response to The Mackenzie Valley Pipeline Proposal and contributed significantly to the Commissioner’s Inquiry. CARC has been involved in subsequent pipeline initiatives on the quest to find an optimal, sustainable solution. If it had been successful, the Mackenzie Valley Pipeline would be the largest infrastructure in the North. CARC assisted in stopping the implementation of this pipeline due to the environmental detriments, which are further described in Chapter 6 (CARC-Canadian Arctic Resource Committee 2017). CARC works to defend and protect the interests of natives and residents of Canada. CARC encourages northern development, while still maintaining the natural landscape and environmental advantages that native people depend upon. CARC acts as a mediator between governmental advancement and native opinions in order to protect both interests and assist in creating appropriate legislature. After its creation, CARC worked on a national treaty for toxic chemicals and ensured that the Canadian diamond mines were made to be as environmentally sustainable as possible. CARC works as an advocate for Northern natives and develops policy for conscientious use of Arctic resources. CARC supports industrialization and development that works with the environmental conditions and contributes positively to the lives of those who reside in that area. In order to help developers understand native land claims, CARC provides cultural information about native peoples. In addition, CARC releases publications including Northern Perspectives, Northern Minerals Program, Compass, and Voices from the Bay, which provide context into the main issues facing the Arctic and its people (Canadian Arctic Resources Committee 2010).

“In my perfect world, I have a competency profile — you know, on LinkedIn, presumably — that is kept up to date in real time on the competencies that I am exhibiting in my work, as well as competencies that I’ve demonstrated through assessments, through my education, the formal credentials that I’ve accrued,”

It’s a very specific dream, but it sounds like it’s shared by a lot of people.

Businesses are not saying "I want someone who went through a programme that promised them a job".

In the Ivory Tower, we hear less about that part of the relationship between Higher Ed. and businesses. Those colleagues of ours who are so against the 100-year push for universities to become more vocational tend to assume that employers are the ones doing the pushing. While it’s quite possible that some managers wish for universities to produce optimised employees, many people on that side of the equation argue that they’re quite able to train employees, as long as they’re able to learn.
Now, there’s a whole thing about the “talent pipeline” which might get faculty in a tizzy. But it’s not about moulding learners into employees. Like much of Higher Ed., it’s about identifying (and labeling) people who conform to a certain set of standards. Not less problematic, perhaps, but not so much of a distinction between academia and employability.
